Hey,

 

Anyone who use to fly with the alabeo c421 know why everytime I hit the autopilot BC this one is turning on and directly off to activate the NAV ? Pretty annoying

 

Thank you 🙂

Hello Bert, thx for your autopilot fix.

I implemented it but the BC button is still not working probably! Since I never use it, it's not that important to me.

But i have another question:
If i am in AltHoldMode and (on the Alt Alert Gauge) i dial a new hight and then push the ARM button, i expect that the AltHoldMode will turn off, but that doesn't happen.

Maybe you have a solution for it?

Best regards
Raller

On some autopilots you have to turn off ALT and select VS before the aircraft will climb or descend..

The solution is most likely that you simply have to dial in vertical speed. With the AP in alt hold, there's no reason for it to cancel itself if there's no vertical mode/speed selected.

Don't know the Alabeo 421 AP system, but if this is only an altitude alerter, it's not even connected to the AP system and hence it doesn't do anything else than to alert you when approaching/leaving the selected altitude.

The thing is, as long as ALT HOLD is selected, i can't change the vertical speed on the AP Pitch wheel. It's locked!

I found a solution and made an entry in the "Gauge_ALT_ALERT.xml". It works like expected and til now i haven't found any negativ side effects.

Maybe Bert can take a look if it's right.

And what happens if you push alt hold a second time? On most APs you can't change the vert speed if the AP is in alt hold ,which is a good thing of course.

...it turns the Alt Hold Mode off.

That's how the AP looks like.

PS: My intention within the Alt Hold Mode is:
1. i dial a new hight
2. i push the ARM button
   (with my modification the AltHoldMode turns off automaticaly)
3. i set the vertical speed with the wheel

After i reach the desired height, the AltHoldMode turns back on again. Works fine...

I am sure that would work fine.. Whether it is the way that the real autopilot behaves, I do not know..  Do you have the factory Pilot's Guide?

No i did not. I just know the KAP140 AP and it behaves like this.

This is a Cessna 800 Integrated Flight Control system..

In the Pilot's Guide it says that to turn off ALT, you have to either push the ALT button (if it is on) or push the Pitch Synch button on the yoke.

I believe that you have created a third way to accomplish this.. :wink:

Makes it a little easier to use 😉

By now it has become one of my favorite ga airplanes in the middle class segment (after some system mods and countless texture bug fixes in the cockpit).

...which luckily are possible (and necessary) at Carenado/Alabeo.
